- Suitable for welding with cellulose electrodes
- Universally applicable for welding all common electrode types
- Best suited for assembly work due to protection class IP 21S generally also for outdoor work
- Suitable for use on generators, for example in workshops, schools, metal construction, on construction sites or for farmers
- Protected against moisture, salt spray and corrosion due to sealed circuit board. Therefore also suitable for offshore use
- Equipped with VRD for voltage reduction in no-load operation
- TIG DC function enables simple TIG welding with contact ignition
- Accurate setting and display of welding parameters via LC display
- Quiet running fan with good heat dissipation for high switch-on times
- Constant welding current achieves consistent deposition rate
- Hot Start: By automatically increasing the welding current for a short time, the arc ignites safely and is immediately stable
- Anti-stick: If the electrode accidentally sticks, the welding current is automatically reduced, thus preventing the electrode from annealing
- Arc-Force control: Due to the internal monitoring of welding current and welding voltage, short-circuits are quickly and safely resolved, thus stabilising the arc and allowing the electrode to be processed without any problems
